Presented are clutch-type engine disconnect devices, methods for making/using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device includes a notch plate, which has multiple notches and attaches to a torque converter, and a pocket plate, which has multiple pockets and attaches to an engine's crankshaft. A pawl is movably mounted within each notch; these pawls selectively engage the notches with the pockets. A notch plate insert is nested within each notch, supporting thereon one of the pawls. A selector plate interposed between the pocket and notch plates moves from a first position, to shift the pawls out of engagement with the pockets, and a second position, to move the notch plate inserts within the notches and allow the pawls to engage the notches with the pockets to thereby lock the notch plate to the pocket plate to rotate in unison with each other.

A pump includes a stator and a rotor axially between a fluid inlet section and a fluid outlet section. The stator includes a plurality of radially inwardly extending legs; and a plurality of electrical windings disposed about the radially inwardly extending legs. The attenuating circuit includes a capacitor electrically wired in parallel with each winding and at least one switch electrically connected to the capacitor. During energization of the electrical winding, the switch electrically connects the capacitor to an electrical ground and the electrical power source creates a voltage in the capacitor. Following a de-energization of the plurality of electrical windings, the switch isolates the capacitor from the electrical ground and the capacitor discharges the voltage through the electrical winding, creating a decaying oscillating current that attenuates residual magnetization in the winding.

A transmission actuator for a vehicle includes a housing, a first rocker for engaging a toothed wheel, a second rocker for rotating the first rocker to engage the toothed wheel, an engagement rod for rotating the second rocker, a solenoid arranged to displace the engagement rod, and a solenoid control circuit. The solenoid includes an iron core, a wire coil wrapped around the iron core, and a ferromagnetic plunger. The plunger is arranged to linearly displace in a first direction when a first directional current is applied to the wire coil, and linearly displace in a second direction when a second directional current is applied to the wire coil. The solenoid control circuit is arranged supply the first directional current when energized by a power source, and supply a decaying alternating current that includes the first directional current and the second directional current when the solenoid control circuit is de-energized.

The invention relates to a coupling device for a drive train of a motorcycle or other motor vehicle, in particular for suppressing a so-called hopping. According to the invention, the coupling device has an output rotation part, a switchable friction coupling, which has an energy storage device for closing thereof and which is closed in an unactuated state, and at least one freewheel coupling for forming a torque transmission path for torque transmission from the input rotating part to the output rotating part, wherein the freewheel coupling includes the following components: an inner rotating element, the outer circumference of which forms a sawtooth-shaped circumferential structure having a plurality of circumferentially extending ramps; a substantially annular plate structure having an individual plate element or a stack of a plurality of plate elements, the inner circumference of which forms a sawtooth-shaped circumferential structure having a plurality of circumferentially extending counter-ramps to form an interlock and/or a friction lock together with the ramps of the inner rotating element in a rotation direction; and an outer rotating element surrounding the plate structure. The invention further relates to a corresponding drive train having such a coupling device.

A wedge clutch assembly for transferring torque from an engine to an output shaft, comprising a clutch carrier comprising an axial friction surface and a radially inwardly facing surface, a hub comprising a first radially outwardly facing surface having grooves positioned circumferentially thereon and detents positioned within the grooves, a wedge plate comprising an axial friction surface, a second radially outwardly facing surface, and a second radially inwardly facing surface having recesses, a pressure plate concentrically arranged within the first radially inwardly facing surface and displaceable such that in an engaged mode, an axial force is applied to the pressure plate, in a first axial direction, to engage the wedge plate with the clutch carrier such that torque is transferred from the engine to the output shaft, and in a disengaged mode, the wedge plate is independently rotatable from the clutch carrier.

A wedge friction clutch with onboard enable and disable function, including: an axis of rotation; an inner race; an outer race; a wedge plate located between the inner and outer races in a radial direction; a first resilient element; and a piston. For a locked mode, the first resilient element is arranged to displace the wedge plate in a first circumferential direction to non-rotatably connect the inner and outer races. For a free wheel mode the piston is arranged to displace in a first radial direction to displace the wedge plate in a second circumferential direction, opposite the first circumferential direction such that the inner and outer races are independently rotatable with respect to each other.

A locking clutch ratchet wrench (1) is configured such that a clutch ring (500) forms the mid part of aminate like structure. Under torque applying conditions, the compression forces applied to the clutch ring (500) are substantially dissipated around the circumference (507) of the clutch ring. This inwardly directed force clamp against the inherently strong outer surface 405 of the drive element (400). The resultant pseudo laminate structure of the drive element (400), clutch (500) and housing (201, 202) enables the construction of a proportionately stronger ratchet wrench of reduced height or width.

A shifting system for a vehicle transmission includes an input member and a selectable one-way clutch rotatably coupled to the input member. The selectable one-way clutch is moveable between first, second, and third clutch positions. The shifting system also includes a disconnect coupled to the input member and moveable between first and second disconnect positions, and an output member selectively rotatable with the input member. The shifting system further includes a shifting assembly for selectively rotatably coupling the input and output members. The shifting assembly includes an input hub coupled to the input member, having a disconnectable component engageable with the disconnect, and having a clutch engagement component. Clutch plates are coupled to the clutch engagement component and are moveable between engaged and disengaged positions. A clutch plate carrier is coupled to the clutch plates and output member to transmit torque from the clutch engagement component to the output member.

A distance (D.sub.1) between a rotation center (O) of an input member (3) and a contact portion (P.sub.in) between an input side engaging portion (9) and an input side engaged portion (17) in a second direction is set to be shorter than a distance (D.sub.2) between a rotation center (O) of an output member (4) and a contact portion (P.sub.out) between an output side engaging portion (12) and an output side engaged portion (14) in the second direction in a state in which a pair of pressing surfaces (13) is pressed against a pressed surface (6) in accordance with a rotation of the output member (4) in a predetermined direction and the input side engaging portion (9) engages with the input side engaged portion (17) in accordance with a rotation of the input member (3) in a direction opposite to the predetermined direction. In a locked or semi-locked state, a contact portion (C.sub.1) between the output side engaging portion (12) and the output side engaged portion (14) is located on the side closer to the rotation center (O) of the output member (4) in a first direction in relation to a virtual line (L) connecting the rotation center (O) of the output member (4) and a contact portion (C.sub.2) between one pressing surface (13) of the pair of pressing surfaces (13) and the pressed surface (6).
